Geert Janssens 83d14e1c1c Restructure the src directory
It is split into
- /libgnucash (for the non-gui bits)
- /gnucash (for the gui)
- /common (misc source files used by both)
- /bindings (currently only holds python bindings)

This is the first step in restructuring the code. It will need much
more fine tuning later on.

* FUNCTION:
* The is the *private* transaction header file. Code outside of
* engine should *not* include this file. This is because code
* outside of the engine should *never* access any of the structure
* members directly.
*
* Note that this header file also defines prototypes for various
* routines that perform sub-atomic updates of the accounting
* structures. If these routines are not used properly, they
* can result in inconsistent, unbalanced accounting structures.
* In other words, their use is dangerous, and their use outside
* of the scope of the engine is forbidden.
